I. Device Description
The MAX11080 is a battery-pack fault-monitor IC capable of monitoring up to 12 lithium-ion (Li+) battery cells. This device is designed to provide an
overvoltage or undervoltage fault indication when any of the cells cross the user-selectable threshold for longer than the set program-delay interval.
The overvoltage levels are pin selectable from +3.3V to +4.8V in 100mV increments, and have a guaranteed accuracy of ±25mV over the entire
temperature range. The undervoltage level is also user selectable from +1.6V to +2.8V in 200mV increments. These levels are guaranteed to ±100mV
over the entire temperature range. Undervoltage detection can be disabled as one of the user-configuration options.
The MAX11080 has a built-in level-shifter that allows up to 31 MAX11080 devices to be connected in a daisy-chain fashion to reduce the number of
interface signals needed for large stacks of series batteries. Each cell is monitored differentially and compared to the overvoltage and undervoltage
thresholds. When any of the cells exceeds this threshold for longer than the set program delay interval, the MAX11080 inhibits the heartbeat signal
from being passed down the daisy chain. Built-in comparator hysteresis prevents threshold chattering. The MAX11080 is designed to be the perfect
complement to the MAX11068 high-voltage measurement IC for redundant fault-monitoring applications. This device is offered in a 9.7mm x 4.4mm,
38-pin TSSOP package with 0.5mm pin spacing. The package is lead-free and RoHS compliant with an extended operating temperature range of -
40°C to +105°C.
